Rubber Expansion Joints

High-Quality, Customizable Rubber Expansion Joints with Standard Compliance and Flexible Solutions

Single Sphere Bellow

Molded single-sphere rubber bellows are designed for the most demanding piping systems, allowing for axial, lateral, and angular movements with easy installation. which directional movement, reducing vibration and noise, and offering various flange materials for flexibility.

Double Sphere Bellows

Molded double-sphere rubber expansion joints are engineered to handle the most demanding piping system setups.Their robust design ensures durability in complex conditions. BodyMaterial:NR,NBR,EPDM,FKM,VITON, BUTYL(IIR), HYPALON,CR(chloroprene)

Full Faced Rubber Joint

Molded wide arch expansion joints feature the lowest spring rates on the market and require minimal force for deflection.Building length: 255 – 550mm BodyMaterial:NR,NBR,EPDM,CR(chloroprene) Flange material:zinc plated carbon steel EN1092 PN6/10 – ASME B16.5 150lbs.

Hand-built Rubber Bellow

KHD Handmade joint Integrated steel flanges and built to withstand even the most rigorous piping system configurations.The pressure can reach 40 bar, and the temperature can reach 190℃.Gives small reaction forces, providing high reliability and long service life.Customizable in any size.

SAE Rubber Compensator

Rubber compensators are elastic connectors with turnable SAE aluminum alloy flanges and a high-quality nitrile bellow. They are suitable for mineral oil products, crude oil, lubrication oil, cooling oil, water, and fuel with up to 30% aromatic content, making them ideal for suction and return lines.

ANSI Expansion Joint

The Songjiang expansion joints have flanges that comply with ANSI/ASME standards, the rubber materials follow ASTM standards, and they meet AWWA standards. This ensures high quality，making them suitable for various industrial and water utility applications.
